WATER-C LOS ET.

SPECIFICATION forming part of Letters Patent No. 408,038, dated July 30, 1889.

Application filed August 29, 1887. Serial No. 248,177. (No model.)

To all whom it may concern:

Be it known that I, GEORGE D. MOFFAT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tater-Closets7 of which the following is a full, clear, and exact description.

My invention relates to closets to be used in railway-cars and in similar places which are without a system of water-supply and in to which precautions must be taken to prevent the disabling of the closet by the formation of ice therein. I therefore provide a closet in which the water is delivered from a tank to the bowl or hopper by a pump actuated by the user of the closet; but instead of operating the pump by the direct application of power to its piston I provide a spring to move the piston in the proper direction to discharge the water and apply the power, in 2o the first instance, to compress this spring. I provide a hinged lid or cover for the hopper and connect the same by intermediate parts with the piston, so that the raising 0f the lid compresses the spring and the falling of the lid permits the spring to react and deliver the water gradually and without assistance from the lid. I make the lid-connections such that the lid may fall independently of the forward movement of the piston, so that in the event of the pump being impeded'by ice the forcible movement of the lid will not break the other parts; and so, also, that, although the pump may be inoperative the lid may rise to permit the use of the closet as a dry closet. I also make the connection between the lid and pump such that the pump is caused to iiush the hopper and iill the pan as the lid rises, and then Iiush the hopper a second time as the lid falls and opens the 4o pan.

IVhile I have demonstrated my invention in its preferred form, it is to be understood that the details may be modied within the range of mechanical skill. The two essential features of the invention are the springactuated pump and means for compressing its spring and the connection of a pump with a lid to flush the closet when the pan opens as well as when it closes, and it is manifest that various connections the mechanical equivalents of these shown may be used to this end.

In the accompanying drawings, Figure l is an elevation of my closet with the water-tank and pump in vertical section and the hopper and pan partlyy in section and in position for use; Fig. 2, an elevation showing the parts in the position assumed after the cover is closed and the contents of the pan are dumped. Fig. 3 is a side elevation of a modi- 6o ication.

Referring to the drawings, A represents a water tank or reservoir of any suitable size and forni, adapted to contain water sufficient to iiush the closet repeatedly.

B is a hopper or bowl of any approved form, located withinthe tank and seated within and securely united to the top of a funnel B', which latter is fitted tightly over and around an opening in the bottom of the tank.

IVithin the funnel, which is enlarged to afford room therefor, is a hinged rising and fall ing pan D, adapted to close upward around the mouth of the hopper and retain abody of water for sealing the same, as usual. rlhe hinge or pivot pin C of the pan is projected through a packed opening in the side of the hopper, and is provided on the outer end with an operating-arm P, having the irregular slot w opening therein, as shown.

A lid or cover O is hinged to the usual seat above the hopper and provided with a rigid depending arm N, which latter is connected by a link N to one end of a lever L. This lever is pivoted at the opposite end to a link M or other support, and provided on one side with a stud R, which enters the slot in the pan-arm P, as shown, so that when the lid is iitted it raises the pan to an operative position beneath the hopper, and vice versa.

E represents a pump-cylinder fixed rigidly in position within the tank or reservoir Yand provided at its foot with ordinary inwardlyopening valves F for the admission of the water, and also provided at its top with a pipe 95 G to deliver the water into the hopper. The cylinder contains a pump-piston H, provided, as usual in single-acting pumps, with upwardly-opening valves for the passage of the Water therethrough. A strong spiral spring I is 10o located in the foot of the cylinder beneath the piston and serves to raise the piston and cause the delivery of the water to the hopper.

The depression of the piston is effected by means of a piston-rod K, which may, of course, be operated by hand or otherwise. In the combination shown the piston rod bears loosely on the top of the piston, so that it may rise and fall independently, and is jointed at its upper end to the lever L operated by the lid. Vhen t-he lid is turned down, it depresses the piston and compresses the spring, and when the lid is turned up it raises the pan to an operative position, and at the same time relieves the piston from downward pressure of the piston-rod, whereupon the spring reacts, and, lifting the piston, supplies water to the hopper and pan. Owing to the fact that the lid isnot coupled rigidly to the piston, the lid is permitted to rise freely and vents thev connections from being broken in the event of ice being formed in the pumpcylinder, so as to prevent the rise of the piston.

In vorder to more effectually cleanse the hopper, I prefer to Hush the same slightly at the time the lid is closed and the pan dropped; and this result I secure by arranging the connections to permit a slight rise of the piston as the lid completes its descent. As shown at Fig. 2, this is accomplished by having the lid-arm N swing past the perpendicular or past the center, so that it imparts a slight depression to the lever L before lifting it to the position shown in Fig. 2.

I believe myself to be the first to connect the lid and the pump so that the lid will operate the pump both in rising and falling, and it is to be understood that the connecting devices may be of any form known to the skilled mechanic adapted to impart the described movements from the lid to the pump.

The invention is not confined to the exact construction and arrangement of parts shown, as they may be variously'modified without departing from the spirit of the inventionas, for instance, the pump-operating mechanism may be connected to a handle or knob instead of to the cover. The piston-rod may be connected to the piston and disconnected from the lever, and the piston may be otherwise moved than by a spring, as by a weighted lever, (shown in Fig. 3,) the object being to permit the ready opening of the cover and the closing of the pan before the water is forced into the hopper.

Having thus described my invention, what I claim is- 1. In a water-closet, the combination, substantially as shown, of the tank, the bowl or hopper, the intermediate piston-pump, the spring applied to actuate the pump anddcliver water to the hopper, and the piston-rod to advance the piston against the resistance of the spring, whereby the spring is enabled to deliver the water gradually in successive charges from the tank to the bowl.

2. Ina water-closet, the combination, substantially as shown, of a tank, a bowl or hopper, an intermediate piston-pump, a spring applied to move the piston to deliver water to the bowl, a piston-rod, a hinged lid or cover, and arms and levers, substantially as shown, connecting the lid and rod to effect the compression of the spring as the liddescends.

3. In a Water-closet, the iiushing-pump having the cylinder and piston, in combination with the spring within the cylinder to actuate the piston, the disconnected rod D, to depress the piston and compress the spring, the lever acting on'said rod, and the hinged lid connected to the lever to depress the same as the lid rises.

Il. In a water-closet, the hopper, the hinged pan, the pump, and the pump actuating spring, combined with the hinged lid and intermediate arms and levers, substantially as shown, connecting the lid with both the pan and pump.

5. In a water-closet, and in combination with the spring, the valved piston-pump, the pump-operating lever, the hinged lid, the arm on the lid, and the connection between the arm and lever adapted to pass the center and thereby cause the operation of the pump as the lid rises and also as it falls.

6. In combination with the pump and its actuating-lever, the lid and its arm, the connecting-link N and the hinged pan, and the pan-operating arm P, having the irregular slot or opening into which a stud on the lever extends.

In testimony whereof I hereunto set my hand, this 15th day of July, 1887, in the presence of two attesting witnesses.

GEORGE D. MOFFAT.
